The invention discloses an automobile power battery preheating method. The method comprises the following steps: executing a preheating request according to an operation instruction; executing an appointment heating mode or an instant heating mode; if appointment heating is executed, judging whether appointment heating setting conditions are met or not, if yes, executing appointment heating, and if not, setting fails and feeding back prompt information of setting failure to the user; if instant heating is executed, judging whether the current battery temperature is lower than a set minimum temperature threshold value or not if the current battery temperature is lower than the set minimum temperature threshold value, executing heating if the current battery temperature is lower than the setminimum temperature threshold value, otherwise, setting to be failed and feeding back setting failure prompt information to a user. The method has the advantages that the battery pack can be heated through power supply of the charging pile, the heating modes are diversified, and the battery temperature can be maintained under the condition that a power battery is not used. The heating mode has animmediate heating mode and an appointed heating mode, a remote terminal or a vehicle-mounted large screen can be controlled, and heating control is more convenient.

    本发明揭示了一种汽车动力电池预加热方法:根据操作指令执行预加热请求;执行预约加热模式或即刻加热模式;若执行预约加热:判断是否满足预约加热设置条件,若是则执行预约加热,若否,则设置失败并向用户反馈设置失败的提示信息;若执行即刻加热:判断当前电池温度是否低于设定最低温度阈值,若是,则执行加热,若否,则设置失败并向用户反馈设置失败的提示信息。本发明的优点在于可通过充电桩供电对电池包进行加热,加热方式多样化,能够在不使用动力电池的情况下,维持电池温度;加热模式具有即刻加热与预约加热两种模式,并且能够远程终端或车载大屏均可进行控制,加热控制更加方便。
